Cool. > I replaced start.elf and fixup.dat, and only those two files, in = 13.2-RELEASE with the ones from 14.0-ALPHA1, and that boots (usually). So the old *.dtb is still in use vs. the newer one for using the pure 14.0-ALPHA* RPi* firmware. For what you report, both with the releng/13.2 kernel. At some point I'll generate the 2 *.dts's from the *.dtb's in the sorted order and diff the outputs. (This does not deal with live adjustments that are also involved.) Does 14.0-ALPHA* have a panic when not changed? In essence the comparison/contrast checks the older kernel ( releng/13.2 ) vs. the newer kernel for the modern *.dtb case. (Unfortunatey, you have the only known test context. So I ask. But you may not want to be the tester for such questions.) > I say usually because sometimes the boot hangs indefinitely between = loading the keyboard USB device and bringing up the network stuff (lo0, = mue0, and ue0), but usually it just pauses there and then continues. = When it does hang, ctrl-alt-del works to try again. Interesting. > As expected, once it's up there are no apparent problems. The wired = ethernet works fine for ssh and freebsd-update. I haven't stressed the = system much so far, but still looks good after half a day of uptime. As you have the only known panic context, could you gather the serial console output for a context that leads to a panic(/reboot loop) when using just the 14.0-ALPHA* firmware (modern *.dtb) and then report it someplace folks can have access to? Absent such evidence, the FreeBSD kernel will stay broken for your type of context using modern RPi* firmware and FreeBSD's kernel. (Presuming the evidence points to the kernel mishandling something badly to cause a reboot loop.) =3D=3D=3D Mark Millard marklmi at yahoo.com
